The following table presents an incremental analysis that has not been completed, assume that the MARR is 10% per year and that the useful life for each alternative is 6 years, equal to the study period. To evaluate the alternatives, they have been arranged in ascending order with respect to the initial investment:

Do nothing A C B. According to the following table, select the best answer.

On your worksheet you will need to show how you calculated the missing ROR value in the table to get credit

	A--> Do nothing	C-->A	B-->C
Capital investment	-$15,000	-$2000	-$3,000
Annual income	4,000	900	460
Annual costs	-1,000	-150	100
Residual value	6,000	-2,220	3,350
ROR	12.7%	10.9%	???

Select one: a. Alt. B b. Alt.A c. Do nothing d. Alt. C
